+  Provides a Alicloud PAI Workspace Default Workspace resource.

+
+# alicloud_pai_workspace_default_workspace
+
+Provides a PAI Workspace Default Workspace resource.
+
+Default Workspace Resources.
+
+For information about PAI Workspace Default Workspace and how to use it, see [What is Default Workspace](https://www.alibabacloud.com/help/en/).
+
+-> **NOTE:** Available since v1.236.0.
+
+## Example Usage
+
+Basic Usage
+
+```terraform
+variable "name" {
+  default = "terraform_example"
+}
+
+provider "alicloud" {
+  region = "cn-hangzhou"
+}
+
+
+resource "alicloud_pai_workspace_default_workspace" "default" {
+  description = "defaultWorkspace"
+  env_types   = ["prod"]
+}
+```
+
+### Deleting `alicloud_pai_workspace_default_workspace` or removing it from your configuration
+
+Terraform cannot destroy resource `alicloud_pai_workspace_default_workspace`. Terraform will remove this resource from the state file, however resources may remain.
+
+## Argument Reference
+
+The following arguments are supported:
+* `description` - (Required, ForceNew) Description of resource description
+* `env_types` - (Required, ForceNew, List) Resource description for environment type list
+* `workspace_id` - (Optional, Computed) Resource Description of the workspace ID.
+
+## Attributes Reference
+
+The following attributes are exported:
+* `id` - The ID of the resource supplied above.The value is formulated as ``.
+* `status` - Resource description of workspace state
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/docs/configuration-0-11/resources.html#timeouts) for certain actions:
+* `create` - (Defaults to 5 mins) Used when create the Default Workspace.
+* `update` - (Defaults to 5 mins) Used when update the Default Workspace.
+
+## Import
+
+PAI Workspace Default Workspace can be imported using the id, e.g.
+
+```shell
+$ terraform import alicloud_pai_workspace_default_workspace.example 
+```
